IMPROVED WRENCH-BAR-HEADING- MACHINE.

www* A The Schedule referred to in these Lettere Patent and making prt of the same.

Know all men by these presents:

That I, LORING GOES, of the city and county of W'orcester, and Commonwealth of Massachusetts, have invented certain newaud useful Improvements in Wrench-Bar-Heading Machines, of which the fol-I lowing is a full, clear, and exact description, reference'being had to the accompanying drawings, forming apart of this specification, in which- Figure 1 represents a plan or top view of so much of a Goes wrench-bar'headng machine as is necessary to illustrate Amy present improvements, and

vFigure 2 represents a section on line A B, iig. 1.v

Toenable thoseskilled in the art to which my invention belongs, to make and use the same, I will describe it more in detail. t Y The nature of my invention consists- First, in the combination, with the stationary bcd which supports the sliding anvil-block, in the wrenchbar-heading machine', patented by myself and A.- G. poes, on the 31st day of July, A. D'. 1S60, of anl auxlliary removable bed, madein two pieces, as hereafter explained.

Second, in the combination, with the removable anvil-bed, of certain adjusting-devices, as and for the purpose hereafter explained.

Third, in the combination, with the removable and adjustable anvil-hed, ofclearing-hoies, as and for the purposes hereafter set forth.

In the drawings- A is the base, upon which a circular or other propershaped bed, B, is placed. In this case the base A has aange, a, within which the bottom ofthe bed B tits.

The under side or bottom of the hed B is cored out, as -shown at G, and is also provided with two openings, b, one on each side.

A recess or opening is cut througlrthe bed B, for

the reception of the upperpart of the auxiliary anvil-bed D, which is composed of two pieces, D' 1). The upper faces of the pieces D 1)' are tlush with the top of the bed B, while they stand or rest upon the base A, as fully indicated in tig. 2 of the drawm s.

lThe inner upper faces or sides of' the pieces D' D are cut out to receive the anvil-block E, which is to be used and opcratedin the manner shown and described inthe patent before referred to. The ends of the pieces D' D are notched or cut out upon their upperinner sides, for the reception of the adjusting-wedges F F, while the bed B is cnt out to receive the outer adj listing-wedges G G.

1n this instance, wedges G G are shown only on one side, but they lmay be used on both sides, if preferred, in lieu of a plate or plates el, being used on one or both sides.

It will be seen that in case the anvil-block E wears loose, the pieces D D can be set nptoward each other, so as to make a good tit again, and that, too,

with but little trouble, all that is required, being to withdraw the inner wedges F slightly, and then drive down the wedges G G, or insert strips l between the backs ofthe pieces D Dand'the bed B, asindicated at d, in the drawings.

By the use of the wedges F, the pieces D' can be set up close tol the anvil-block E, without danger of binding.

If preferred, in `any case, strips d and wedges G may be used on both sides at the same time.

It will be understood that the shank of the wrenchbar is to be inserted in the opening e of the anvilblock E, and the slide-dies H H` operated from eccentrics or cranks on the upright shafts I I, (only the lower ends of which are shown in the drawings,) the same as in the machine patented by A. G. Goes and myself, and to which reference has been made.'

In the patented machine last referled to, the anvilblock E works on ways formed in the bed B, sov that when the said ways are worn badly, there is no alten native but to replace the entire bed B, by a newone, thus involving a great expense.

Then, again, the jarring occasioned by the falling 0r action of the upper hammer or die, (not shown in the drawings,) when the anvil-block rests upon ways formed in the eleva-ted bedpiece B, creates much more injury to the working-parts of the machine than what it does when the anvil-block rests and moves upon ways formed in independent and separate pieces supported upon the base-piece A, as shown in the drawings.

If the anvil-ways in the pieces D D become worm so that the anvil works too low, narrow strips of metal can be placed under said piece, and thus elevate the anvil-block to the proper height again.

During the operation of heading the wrench-bar, scales are thrown o" and fall down upon the ways ff.

lThe scales thus thrown off, are very hard, Aand are liable to work under the anvil-block, and thus greatly increase the wear of the ways fk f, as well as the uuder side ofthe anvil-block. 4

To guard as much as possible against such iuj urions results in the operation of the machine, -I make a hole,

g, shown in dotted lines, at each end of cach piece D', the hole g leading from the ways f down into the open space under the bed B. `By this arrangement the anvil-block, as it moves back and forth, has a tendency to clear the ways f, by forcing the scales'over and into said holes, and through which they pass or fall down under the bed B.

There is an opening, J, under the centre ofthe anvil, the same asin the original Goes heading-machine, but in practice, that has been found insuicient to prevent the diiiiculty,wl1ich is obviated by clearing-holes g.

It will be seen from-the foregoing description, that by my present improvements, the value of tlie' original Goes wrench-bar-heading machine is greatly enhanced, since the machine will last much longer, while, at the same time, the adjustment of the devices which retain the anvil-block in place can he so readily' and accurately made, that there is no danger of the niachine making imperfect heads, as is the case in the original machine. v

Having described my 'improved wrench-bar-heading machine,

What I claim therein as new and of my invention, and Vdesire to secure by Letters Patent, is-

1. The combination, with the stationary bed B and base A, of the auxiliary removable bed D, substantially as and for the purposes set forth.

2. The combination, with the parts D D' constitially as described.
